Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radio communication device such as a mobile phone and a mobile transceiver.

[0002]

2. Description of the Related Art In recent years, mobile radio communication devices have come into wide use as their convenience and economy have improved.

A conventional portable wireless communication apparatus will be described with reference to FIGS. 2, 3 and 4 by taking a portable wireless communication apparatus of a type in which a power source of a main body is turned on / off in response to expansion / contraction of an antenna as an example. To do. FIG. 4 is a perspective view of a portable wireless communication device,
FIG. 2 is a block diagram showing a circuit configuration of the device shown in FIG.
However, the attached circuit and the connection circuit of the external device are omitted.

Referring to FIG. 4, a conventional portable wireless communication device includes a keyboard 1 for inputting numbers and symbols on a surface of a main body 1, a display section 5 for displaying the input numbers and symbols, or an operation function. A speaker 6 and a microphone 7 as a transmitting means are arranged. On a side surface of the main body, a first power switch 3 for operating turning on / off of the main body 3, and a transmitting / receiving antenna (hereinafter referred to as an antenna) on an upper end surface. When the antenna 2 is provided and the antenna 2 is expanded and contracted, the power of the main body 1 can be turned on and off like the first power switch 3.

In FIG. 2, a speaker 6 is connected to the inside of the main body 1 via a receiver circuit section 9 and a microphone 7 is connected to it via a transmitter circuit section 8 and is controlled by a control circuit 11. . Further, the antenna 2 is connected to the receiver circuit unit 9 and the transmitter circuit unit 8 via the antenna duplexer 10. Further, the storage battery 13 is turned on / off by the first power switch 3 or the second power switch 2b interlocking with the antenna 2 via the power control circuit unit 12, and the receiver circuit unit 9, the transmitter circuit unit 8 and the control circuit 11 in the main body 1 are turned on and off. Etc. are connected to each part.

The operation of the above apparatus will be described with reference to FIG.
First, as an operation using the mobile phone, when the storage battery 13 is connected at the timing T1 in the timing chart of FIG. 3B, the power is initially set to OFF by the system reset. By extending the antenna 2, the second power switch 2b is connected, power control is turned on at timing T2 in the figure, and power is supplied from the power control circuit unit 12 to each unit of the main body 1. In this state, the keyboard 4 can be operated to make a call. Further, after the call is ended, the call is ended by operating the keyboard 4. To turn off the power after the end of the call, the first power switch 3 is pressed once as at timing T3 in FIG. 3B or at timing T5 in FIG.
By housing the antenna 2 as described above, the second power supply switch 2b is cut off, and the power supply from the power supply control circuit unit 12 can be cut off to complete the use of the device. Other timings are as shown in FIG. 3B, and detailed description thereof will be omitted.

[0007]

However, in the portable radio communication device having the above-mentioned conventional configuration, in order to terminate the use of the portable telephone by turning off the power supply from the power supply control circuit section 12, the above-mentioned method is used. The antenna 2 may be housed or the first power switch 3 may be pressed once. The procedure for starting the use next is after the use of the mobile phone is completed by housing the antenna 2, It is also possible to press the first power switch 3 once to start using it. In other words, the antenna 2 is often started to be used while it is housed, and there is a problem that the device is not used in an optimum state.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a portable wireless communication device that can always perform wireless communication operation in an optimum state.

[0009]

In order to achieve the above-mentioned object, the present invention is constituted by means which can be used only when the power of the portable radio communication device is turned on unless the antenna is extended.

[0010]

With the above structure, it is possible to prevent the power supply from being turned on while the antenna is housed in the main body of the portable wireless communication device to be in a call state.

[0011]

FIG. 1 and FIG. 2 show an embodiment of the present invention.
Will be described with reference to.

FIG. 1A is a perspective view showing a portable wireless communication device according to an embodiment of the present invention, and FIG. 1B is an enlarged view of a part of FIG. 1A.

1A is different from the conventional example shown in FIG. 4 in that it has a sliding knob 2a for expanding and contracting the antenna 2 and a first power source arranged inside the sliding knob 2a. The point is that the switch 3 is provided. Since the other parts are the same as the conventional example, the corresponding components are designated by the same reference numerals and the description thereof is omitted.

Since there is no particular change in the block diagram showing the internal structure described with reference to FIG. 2 in the conventional example, the description thereof will be omitted. Similarly, the logic circuit principle diagram and its timing diagram in the circuit configuration of the power supply control circuit portion of FIG. 3A and the timing diagram thereof, and FIG.

When the antenna 2 is housed in FIG. 1 (a), the first power switch 3 is located behind the sliding knob 2a, so the first power switch 3 cannot be operated. When the antenna is extended in 1 (b), the first power switch 3 is exposed, so the first power switch 3
Has the operation and function of becoming operable. Operations such as call start and call end are exactly the same as those in the conventional example, and therefore description thereof will be omitted. Further, in order to turn off the power after ending the call and finish using the mobile phone, the power can be turned off by pressing the first power switch 3 once or by housing the antenna 7.

As described above, according to the portable radio communication apparatus of the embodiment of the present invention, the sliding knob for extending the antenna is provided and the first power switch is arranged at the back thereof, so that the antenna is not extended. , The first power switch is inoperable and no power is supplied to the device.

It should be noted that instead of the sliding knob, a lid may be provided to cover the first power switch, and the lid may be opened and closed by expanding and contracting the antenna.

[0018]

As is apparent from the above-described embodiments, according to the present invention, the antenna 2 is always extended when the power is turned on, so that the call operation is performed with the antenna 2 housed. It is possible to provide a portable wireless communication device that can be easily used by anyone who does not lose call efficiency due to an erroneous operation.
